The December 31, 2022 Condensed Consolidated Balance Sheet data was derived from audited financial statements but does not include all disclosures required by GAAP. The following information is unaudited. All per share amounts assume dilution unless otherwise noted. This report should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2022. In the opinion of management, all adjustments necessary for a fair statement of this information have been made, and all such adjustments are of a normal, recurring nature. We conduct our business through three reportable segments: Live and Historical Racing, TwinSpires, and Gaming. We aggregate our other businesses as well as certain corporate operations, and other immaterial joint ventures, in All Other. We report net revenue and operating expense associated with these reportable segments in the accompanying Condensed Consolidated Statements of Comprehensive Income.

We will continue to monitor for new developments related to the pandemic and assess these developments to maintain continuity in our operations.
